Converting a string to FileTime in java

I have this problem. PROBLEM: I am making a program in which i am taking input from user via a JFormatedTextField i.e. in string format and then i want this value to be creation time of a file chosen by user.

So I need to uses setTimes() function which only accepts fileTime format. So the PROBLEM is:::: how do I convert the string into an eligible fileTime so that it can be used by the function setTimes() which is predefined in .nio.attribute.

Depending on what the format of the input is (I suppose it is something like "dd/MM/yy HH:mm:ss"), you can convert this to a Date using SimpleDateFormat, from the Date you can get the milliseconds using Date.getTime() and finally use that value to build a FileTime with java.nio.file.attribute.FileTime.fromMillis(long)

Something like this should do it:

String text = textField.getText();
Date date = new SimpleDateFormat("dd/MM/yy HH:mm:ss").parse(text);
FileTime time = FileTime.fromMillis(date.getTime());

This would do the trick:

You have to change the date format (new SimpleDateFormat(...) like you give it in the text field and remove the main method indeed.

    public static void main(final String[] args) {
// TODO Auto-generated method stub
String date = "01.01.2013 10:00:10";
long milis;
try {
    milis = new SimpleDateFormat("dd.MM.yyyy hh:mm:ss").parse(date)
        .getTime();
    FileTime fileTime = FileTime.fromMillis(milis);
    System.out
        .println("Time: " + fileTime.toString());
} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
}
